This invention relates to locking means which enables relatively movable parts to be connected together and disconnected without it being necessary to open the casing in which they are fitted said pin in the position shown connects the two parts 4 and 8 of the locking bolt together in such a way that (in consequence of the corresponding dimensions of the chamber 9, the pin and without requiring a device operable from the ill and the transverse bore 6) the two parts can outside to remove the coupler. only move together.

To effect the reversal of two parts relatively to When it is desired to reverse the lock bolt, the one another, hitherto it has been necessary either lock as a unit is turned upside down. In this to open the casing containing the locking device position the pin If! in the chamber 9 falls to or to provide means operable from outside the such an extent that the coupling, between the 10 casing and requiringaspecial tool for the purpose. two lock bolt parts 4 and 8, is removed. It is The device according to the invention may be then possible to withdraw the part 4 of the lock applied, for instance, to a door-lock, in which bolt outwards so that it may be turned to the case the lock bolt, in order to make the latter reversed position with regard to the part B. When reversible so as to adapt the lock for either rightin this position the pin portion 5 of the part 4 hand or left-hand closing doors, is formed in is inserted again in the bore 1, the pin [0, after two disconnectable parts, these parts being proagain reversing the entire lock to the upright vided with a locking member by which means position, falls again into the bore 6 whereby the the outwardly extending part of the lock bolt can coupling of the two lock bolt parts is again obbe withdrawn from the casing, reversed and tained. re-connected. The pin l 0 may also be made bipartite, whereby In one arrangement of the device as applied to the longitudinal dimension of the chamber 9 may a door-lock, the locking bolt is formed in two be reduced. parts, which latter are adapted to be connected In the bore 1 of the part B of the ock b t together by means of a coupling or locking pin is another pin II which is pressed against the which is a freely movable body. This pin under pin 5 by a plate-spring l3 reaching into a recess the action of gravity may be moved from the lock- I2 in pin ll. After the coupling has been reing position into a position in which the two moved in the manner described and the lock bolt parts are disconnected, whereby the projecting part 4 with the pin 5 is drawn out of the lock, bolt portion can be withdrawn from the casing, the plate-spring l3 pushes the pin ll so far into reversed, replaced into position and reconnected the bore 1 that the chamber 9 is closed and the to the other portion. enclosed pin ID cannot return to the locked po- In order that the invention may be clearly unsition until by the insertion of the pin 5 the derstood reference will now be made to the acpin II is again pushed back.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:-

1. A locking device comprising a bipartite lock bolt, one part having a bore therethrough and the second part having a stem engaged in said bore with a hole passing laterally through the stem and continued axially as a recess in the first part of the bolt, and a freely movable body within said hole and recess.

2. A locking device comprising a bipartite lock bolt, one part having a bore therethrough and the second part having a stem engaged in said bore with a hole passing laterally through the stem and continued axially as a recess in the first part of the bolt, and a freely movable pin within said hole and recess.

3 A lock for doors and the like comprising a bipartite lock bolt, one part having a bore therethrough and the second part having a stem engaged in said bore with a hole passing laterally through the stem and continued axially as a recess in the first part of the bolt, a freely movable body vvithin said hole and recess, a second pin that is engaged in the bore and abuts the end of the stem and a spring with its free end engaging with the second pin.
